The San Diego Chargers placed LB Donald Butler (elbow) on the Reserve/Injured list Monday, Dec. 15. They also signed practice squad CB Greg Ducre to their active roster and free-agent QB Brad Sorensen (Titans) to their practice squad. The terms of Ducre's deal were not disclosed.

San Diego Chargers LB Donald Butler (elbow) suffered a dislocated elbow in the team's Week 15 game. Head coach Mike McCoy said Butler is a candidate for the Reserve/Injured list, but the team has not made a decision yet.

San Diego Chargers FS Eric Weddle has taken over the defensive play-calling duties in the last two games, which means he is the one communicating with defensive coordinator John Pagano on relaying play calls to the rest of his teammates. LB Donald Butler was in that role earlier this year, but Butler's playing time has decreased, and Weddle has plenty of experience. The Chargers are 2-0 since the switch and have played more consistently on defense.
